StuG's Sensi Seeds Black Lights CBD Auto

Hello everyone! Following the relatively successful Zkittlez grow I did a couple of photoperiods (Bubba Kush) that also went well, and after a 2 month break, have just started my 4th grow, and 2nd diary. On 11.12.2020 I popped 3 Sensiseeds Black Lights CBD/THC autos into a wet paper towel and less than 48 hours later, had all three come through with some strong results! On 14.12.2020 I filled my Airpots with pre-wetted Biobizz Allmix, and planted the germinated seeds. By evening on the 15.12.2020 the third seed had popped out, so, a full house, with all showing their cotyledons and tiny first leaves so, the TS1000 went on (at 25%) and so did the clip-on fan. Temps are 25C and RH ~70%. Lighting left on 24 hours for first day. And so we begin, and I hope this is a fuss-free as the last autos, the Zkittlez, which were my first ever run. For this run, I intend to start nutes at around week 3 or 4, and will be using Biobizz Fishmix this time, instead of grow, although my local hydro store said it's OK to use Grow and Fishmix together, but half ml/L of each to make up what would be the 1ml/L total. I'm not sure. I may just stick to Fishmix. I have time to research a bit more and if anyone can help, please do chip in!! Looking forward to this!! 😀
